On the Broncos’ 17th offensive snap Sunday afternoon, they finally managed a simple accomplishment. They found themselves, for the first time, on the Los Angeles Chargers’ side of midfield. The 45-yard line, to be exact. Instead of chugging any further, though, running back Javonte Williams fumbled and the first real drive of any promise for Denver was snuffed before it had a chance to develop. So, too, were the Broncos’ chances in any realistic way a few minutes later when Los Angeles punched home a backbreaker of a touchdown with a minute to go in the first half. The Chargers dominated the opening 30 minutes so thoroughly that the 23-16 final count in their favor didn’t really tell the story. This sequence did. “We did all the things you can’t do in a game like that,” head coach Sean Payton said.
